• Title: Assessing News Thumbnail Representativeness: Counterfactual text can enhance the cross-modal matching ability
• Authors: Yejun Yoon, Seunghyun Yoon, Kunwoo Park,
• Abstract summary: We focus on whether a news image represents the actors discussed in the news text. We introduce NewsTT, a dataset of 1000 news thumbnail images and text pairs. We propose CFT-CLIP, a contrastive learning framework that updates vision and language bi-encoders according to the hypothesis.

• Abstract: This paper addresses the critical challenge of assessing the representativeness of news thumbnail images, which often serve as the first visual engagement for readers when an article is disseminated on social media. We focus on whether a news image represents the actors discussed in the news text. To serve the challenge, we introduce NewsTT, a manually annotated dataset of 1000 news thumbnail images and text pairs. We found that the pretrained vision and language models, such as BLIP-2, struggle with this task. Since news subjects frequently involve named entities or proper nouns, the pretrained models could have a limited capability to match news actors' visual and textual appearances. We hypothesize that learning to contrast news text with its counterfactual, of which named entities are replaced, can enhance the cross-modal matching ability of vision and language models. We propose CFT-CLIP, a contrastive learning framework that updates vision and language bi-encoders according to the hypothesis. We found that our simple method can boost the performance for assessing news thumbnail representativeness, supporting our assumption.

  News Image Captioning requires describing an image by leveraging additional context from a news article. We propose to use the pre-trained vision and language retrieval model CLIP to localize the visually grounded entities in the news article. Our experiments demonstrate that by simply selecting a better context from the article, we can significantly improve the performance of existing models.

  We leverage a noisy dataset of over one billion image alt-text pairs, obtained without expensive filtering or post-processing steps. A simple dual-encoder architecture learns to align visual and language representations of the image and text pairs using a contrastive loss. We show that the scale of our corpus can make up for its noise and leads to state-of-the-art representations even with such a simple learning scheme.

We address the first challenge by associating words in the caption with faces and objects in the image, via a multi-modal, multi-head attention mechanism. We tackle the second challenge with a state-of-the-art transformer language model that uses byte-pair-encoding to generate captions as a sequence of word parts.
